These bi-directional meters from IVY METERING display three readings: Import,export and Net (import deducted from Export). Widely used in the fields of EV charging and PV solar power generation.
1.Introduction
"EM118089/90/91" series bidirectional energymeters are designed for DIN-Rail installation, suitable for grid-connected PV solar energy metering projects and EV charging metering solutions, the meters can measure and display various important power parameters, and can be passed through The RS485 communication port reads the data of the meter in real time. The meter has passed the approval of MID, EMC, and LVD. The bi-directional energy measurement makes the meter an excellent choice for solar metering.
